cultivator is shown, in which it fwill'only be a necessary to consider *the horizontal {and longitudinally extending framefm'emher 5 to whichis connectedthe transversely extending members 6." Thefr'ame' s carried on a suitable axle 7 having journaled thereon the wheels 8. Standards 9 are secured'tothe cross members 6 of the frame, by the U-shaped clips 10 which embrac'ethe members 6 and standards 9 and are clamped theretohy the clamping plate 11, moved and held in" placeby the nuts12 threaded on the ends ofthe clip; 10. 'The standard 9 has secured thereto ad jacent its lower end a memher 13 which may be in the: form of a casting, which extends forwardly from said standard and has a slot 13a extending horizontally therein. Astr d 14;.is clamped in said slot by the'nuts 1 5 threaded thereoinand a disk 16 is rvol'ubly mounted on said stud 14. The memberlii is rle'cessedto ,fit over the standard' 9 and "is clamped thereto by the plates 17 and 18, the latterof which-overlies member 13, said mem hers 17 and 18 heingclamped to the standard 9' and against membcrf13 by the headed and nutte'd bolt 19.. The members 17 and 18 are formed with rearwardly projecting portions which are spaced and between which is pivoted by the headed and nutted bolt '20 the forward. end of a shield 21. x As shown", this shield has arlower edge 21c extending downwardly and merging on a curve'with a horizontal rear portion. The rear edge of the shield isshown as vertical and the top edge Q'lbtbereoffor the greater portion is horizontal, the same sloping downwardly slightly at its forwardend to the pivot 19.

Said shield at its widest portion is inclined upwardly and laterally, as shown in Figs. 3 and 4; The shield 21 has a plurality of spaced holes 21a adjacent its top edge, into any one of which may be connected the bifur level.

cated end 22a of a rod 22, by means of the bolt 23 provided with the wing nuts 24. The rod 22 extends upwardly and through a block 25 having reduced end portions journaled in the parallel sides of the bracket 26 clamped to the standard 9 by the headed and nutted bolts 27. Rod22is threaded atits upper end and arranged with a nut 28 forming a stop. A compression coil spring 29 surrounds rod 22, bearing at one end against a nut on said rod engaging the end 22e thereof, and a-t its upper end against the block 25. Rod 22 has holes 22?) therethrough for receiving cotter" pins and holding shield. 21 raised if desired. Pins 20a between members 17 and 18 form stops limiting the movement of shi el d 21..

The horizontal frame members 6 inatherear havestanda-rds-SO secured thereto bythe clips 31, and clamping bolts 82similar to the. clips and plates -1.0"and 11* already described, which standards 30 are shown as offset rearwardly and having secured to their lowerends the shovels or shares-33.

In operation the disks lfiwil'li be arranged .in pairs, as shown, the members 13 being. ar-

rangedv in oppositely disposed pairs so: that. the rl-isks l ddiverge at theirurear ends. The rows. of. plants 34 thus have the disks and? shields 2.1- at either side thereof, while the shares 33travel centrally betweenzthe rows of. plants. Int-he cultivation of the beets,.when the plants are quite small, the cultivator will. be'used having the disks,.shares and shields the-mon. The shieldsfll. are adapted-to'move some. distance into the ground as shown-1 in Fig. 1.. The'shie-lds movealong in. the groove or furrowcut by thedi sks 1.6 andif. any Weeds or other obstructions are encountered, the. shields will. ride upover the same; dueto theflIlCllIlOd lower edge compressingthe spring- 29; hen. the obstruction is passed, the. shields will: be mm'cd downward into. the: proper. position. Asthe disks. movev along, they cut a groove, turningthedint away from. the'pla-nts, and the. dirt. betweenthe rows and v any. weeds growing betweenthe rows'are. cut: by theshares which. substantially levelther ground thrownnp the disks. The: dirt. moved tothe sides by the sharesis kept: from.

.- covering. up the plants by the shields 21 The dirt fallingagainst the inclined. sides offthe. shields which. slope. upwardly away from the shares,. slides down. the shields as theymove along..and is thus-kept. from falling on the.

'. plants. The inclinationof the shields is thus quite important The second cultivation. also: uses the parts as already described. Vlfhenit is-necessary to block and thin. the beets the. shovel. is raised; upward. thus putting: it. in a position. where it is not. in contact with the soilandonly the disks are in operation, cutting'away the dirtfrom the beets and-laying. it aside, fillingthe groove formerly made by the large shovel-e This leaves the ground- Aiften this-cultivation it isthen com mon to have the laborers, such as the Mericans, block out the beets, leaving plants eight to ten inches apart. After the beets are blocked and thinned the shovel is again turned down for cultivation. This is the very most important time when the disks should be.on,.as the combination of the. two,.namely, the disk iand. shield, are. most needed to protect the beets, for at this time the beets are in their most delicate condition. The disks and shovels are both used until the leaves of the plants have grown out between the rows so thatthereis'danger of cutting olf the leaves with the disks. Then and not till then are the disks removed andthe shields raised so as to. allowthee dirt to be; thrownainongst. the beetsby the shovels. With applicantls, construction these disks canreadily. be removed merely removing the bolt or stud 15: The beetstarethns cultivated as often as time will permit,.with.jnst the shovels... This throwsup a ridge along. the rows,.leavihg a depression in the center, as indicated by the line 35in Fight. hen. thedisksare used,tlie. same tendtothrow up. a ridge between the rows, leaving: a. depression. adjacent the rowsas slmwnby the line 36. in- Fig. l.

From. the above. description, itis seenthat applicant has provided avery simple andiefii cient structure and one which; enables the disks l6 tobe quickly removed .and. replaced, and one whichnproduces avery effective shield forprotectingthe'beet plantsfrom the dirt moved: by the. shovels. With. thisarrangement it is possibleto. do rapid. work and to take care ofamnch. largerareaof beets. It will be readily seenthat. applicants means secured to thebottom oftliestandardt), shield 21. and its holdin gparts, including rod 22 and bracket 26 can be applied: to a standard cultivator... The invention. thus forms acon venientattachments. and: one adding greatly to the efficiency ofthe cultivator.. Thedevice has been amply demonstrated in actual practiee and found; t orbe very successful: and eflioient.

It will, of courseabe understoodthat v arious changes may be made:in theform, details, arrangement and proportions of the parts,-withoutdeparting'from the scope of applicant"s invention, which, generally stat ed, consists in adevicec'apa'ble'of carryingout the obj ectsabove set forth, i irthe novel parts and combinations ofparts. disclosed and defined" in "the append ed claims.
